TypeJailbreaking
Websitepalera.in

palera1n is both a tethered and a semi-tethered jailbreak for devices vulnerable to the checkm8 bootrom exploit running iOS/iPadOS 15.0-17.3. This jailbreak supports both rootful and rootless modes via an argument (apart from iOS/iPadOS 17, which only officially supports rootless mode).

palera1n Legacy (or 1.x) is deprecated and no longer maintained by it's original authors due to the introduction of palera1n-c (or 2.0.0 beta), which utilizes checkra1n's 0.1337.x builds to boot into pongoOS - however, using its own components (such as binpack, overlay, kpf, fork of pongoOS) to help it boot into the jailbroken state.

Due to the nature of checkra1n, palera1n-c (or 2.0.0) dropped support on making an option for it also to be a tethered jailbreak, unlike palera1n Legacy (1.x) which doesn't use checkra1n.

Supported devices

Note: On A10(X) and A11 devices, the passcode must be disabled while in a jailbroken state. On iOS 16, those SOCs require erasing the device before use. Using palera1n 2.0.0 allows the use of a passcode if on A10(X).

  • Fixed rootless --force-revert issue not being able to find boot hash.

    • This only works if a snapshot is created when fakefs is created, so it will only work if fakefs is also created with release or a newer release.

2.0.0 beta 8 26 October 2023

Highlighted changes

  • Support for 17.0 - 17.1 (and potentially higher)
    • "Rootful" type jailbreak will not be officially supported by us on these versions.
  • Loader now has (limited) json functionality, which now we can change the configuration on where the loader would download from without needing a new beta.
    • By limited, we mean there is no functionality in place to update the packages or repositories that the helper installs/adds (yet). However, bootstrap/package managers are working currently.
    • Proper documentation for this soon.

Loader

  • Downloaded content is now in /tmp/ due to potential permission issues from other jailbreaks.
  • Changes some loader internals to accommodate for json loading changes, this includes having some optimizations for the interface.
  • Cleanup of useless files/directories being created that were there for development purposes.
  • Upon using --force-revert, --clean-fakefs, and "Revert Install", it now deletes leftover Zebra files.
  • Helper will no longer try to write to Zebra's sources.list to add palera1n's default repositories, rather now you should use Zebra's built in community sources page for default repos.

CLI changes

  • Update checkra1n version to 0.1337.2
  • Log info will no longer show the user their device UDID when going in to recovery mode, unless user has specified having double verbose in their arguments (-vv).
